Gegenstand der Erfindung ist eine Teigtheilmaschine, welche sich dadurch kennzeichnet, dais sämmtliche Bewegungen, wie das Oeffnen und Schliefsen des Deckels, das Aufurid Abwärtsbewegen der Theilmesser u. s. w. selbstthätig von einer Antriebswelle aus erfolgen, derart, dais der die Maschine Bedienende weiter nichts zu thun hat, als den Teig in den Teigbehälter zu bringen und eine zwischen der Antriebswelle und dem beiliebig angetriebenen Vorgelege eingeschaltete Kupplung einzurücken. Es ist ferner die Anordnung derart getroffen, dafs diese Kupplung nach Beendigung des Arbeitsganges selbstthätig ausgerückt und die einzelnen Theile wieder in ihre Anfangsstellung zurückgebracht werden. Im Uebrigen ist die Wirkungsweise der Maschine der Hauptsache nach dieselbe wie bei den bisher bekannten Teigtheilmaschinen, bei denen nach Pressen des Teiges der Prefsstempel durch Messer durchdrungen und der Teig getheilt wird.The subject of the invention is a dough molding machine, which is characterized by the fact that all movements, like that Opening and closing the lid, moving the dividing knife up and down, and so on. take place automatically from a drive shaft in such a way that the operator of the machine has nothing more to do than to put the dough in the dough container and one in between the drive shaft and the optionally driven back gear to engage the engaged clutch. Furthermore, the arrangement is such that this clutch is terminated of the work process automatically disengaged and the individual parts back into their own Initial position to be returned. The way the machine works is by the way in the main the same as with the previously known dough-making machines which after pressing the dough of the press punch penetrated by knife and the Dough is divided.

Die beiliegende Zeichnung veranschaulicht in den Fig. 1 bis 4 ein Ausführungsbeispiel in einer Vorderansicht, zwei Seitenansichten und einem Grundrifs.The accompanying drawing illustrates an exemplary embodiment in FIGS in a front view, two side views and a basic riff.

Die Antriebsvorrichtung ist am hinteren Ende des Rahmens 1 in Höhe des Teigbehälters 21 angebracht; sie besteht aus der in den beiden Lagern 35 und 36 geführten Welle 37, auf welcher sich die Riemscheibe 38 lose dreht. An der inneren Seite ist letztere mit Klauen 52 ausgerüstet, und bildet auf diese Weise eine Hälfte einer Klauenkupplung. Die andere Hälfte dieser Kupplung wird gebildet von einer auf der Welle 37 verschiebbaren Hülse 40, welche an den der Riemscheibe 38 zugekehrten Enden ebenfalls mit Klauen 39 ausgerüstet ist. Die Einrückung dieser Kupplung erfolgt von dem Fufstritt 46 aus, welcher drehbar am Maschinengestell aufgehängt ist und durch das Gestänge 47 mit einem auf der Antriebswelle 37 gelagerten Hebel 45 derart in Verbindung steht, dais der letztere bei Abwärtsbewegung des Fufshebels 46 aufwärts bewegt wird und so dem mit ihm fest verbundenen Ring 44 eine Drehung in der Uhrzeigerrichtung ertheilt.The drive device is at the rear end of the frame 1 at the level of the dough container 21 attached; it consists of the shaft 37 guided in the two bearings 35 and 36, on which the pulley 38 rotates loosely. On the inner side is the latter with claws 52 equipped, and in this way forms one half of a dog clutch. The other Half of this coupling is formed by a sleeve 40 which is displaceable on the shaft 37 and which is attached to the belt pulley 38 facing ends is also equipped with claws 39. The engagement of this clutch takes place from the footstep 46, which is rotatably suspended from the machine frame and through the linkage 47 with a lever 45 mounted on the drive shaft 37 is in such a connection that the latter is in connection with the downward movement of the foot lever 46 upwards is moved and so the ring 44 fixedly connected to it gives a clockwise rotation.

Wie aus Fig. 4 zu erkennen, besitzt dieser Ring 44 an seinem äufseren Ende eine schräg verlaufende Aussparung, in welche ein am Maschinenrahmen fester, entsprechend geformter Ansatz 43 hineinreicht. Bei der durch Abwärtstreten des Fufshebels veranlafsten Drehung des Ringes 44 gleitet die Aussparung des letzteren an dem erwähnten Ansatz 43 entlang, so dais der Ring 44 zusammen mit dem Hebel 45 nach innen verschoben wird. Hierdurch wird auch die den verschiebbaren Theil der oben erwähnten Kupplung 39, 52 bildende Hülse 40 entgegen der Wirkung der in dieselbe eingelassenen Feder 41 nach innen verschoben und die Kupplung somit eingerückt. Die Hülse 40 ist in bekannter Weise durch einen Keil 53 zwangläufig mit der Antriebswelle verbunden, so dais die letztere nach Einrückung der Kupplung mitgenommen wird, wenn die Riemscheibe 38 entweder direct oder durch Vermittelung eines anderen Vorgeleges inAs can be seen from FIG. 4, this ring 44 has an oblique angle at its outer end running recess in which a correspondingly shaped fixed to the machine frame Approach 43 extends into it. When the ring 44 is rotated by stepping down the foot lever, the recess slides of the latter along the mentioned extension 43, so that the ring 44 together with the lever 45 is displaced inward will. This also becomes the sliding part of the above-mentioned Coupling 39, 52 forming sleeve 40 counter to the action of the embedded in the same Spring 41 shifted inwards and the clutch is thus engaged. The sleeve 40 is positively connected to the drive shaft in a known manner by a wedge 53, so that the latter is taken along after the clutch is engaged when the pulley 38 either directly or through the intermediary of another transmission in

Claims

Rotation is offset. From here the movement is transmitted through the intermediary of the chain wheels 50 and 4 and the chain 49 to the main shaft 2 of the machine, from which the individual parts are set in motion. The drive of the prefilling plate and the dividing knife takes place, for example, as shown in the drawing, by means of a crank, whereby after the pressing has occurred, the prefixing ram remains behind from an attachment due to a structural part sliding off. The lid is moved in the manner described below. With the usual dough dividing machine !!, in which, as is known, the individual work processes were carried out one after the other by hand, the worker had to remove his hands from the dough container after placing the dough in order to close the lid. With the mechanical drive, this need is no longer necessary, and there is therefore the danger that the worker will remove his fingers too late from the dough container and be injured by the flipping lid. To prevent this, the following arrangement is made: The movement of the cover occurs from the crank 5 wedged onto the shaft 2, in such a way that a pin 8 fastened to the latter, during the lower part of its circular movement, moves onto the free end of the double-armed one mounted at 10 Lever 9, 11 acts. The latter is connected to the cover by a resilient linkage 12, 13, 18 in such a way that the movement is only transmitted by means of the spring 18. By suitable choice of the strength of this spring, the possibility is given to hold the cover 16, although the machine is already in progress or. while the double-armed lever 9, 11 is swung out by the crank pin 8. In order to give the machine operator a warning signal, so to speak, the device is designed in such a way that the lid does not close completely all at once, but first stops at a certain distance above the dough container, makes a short upward movement and only then falls completely. This is achieved by the peculiar shape of the free end of the double-armed lever 9, 11 mentioned above. During its downward movement, the crank pin 8 first comes to rest on the part 20 of this lever arm, which is so shaped that the cover only comes into the position indicated by dash-dotted lines in FIG. As the rotation continues, the crank pin enters the bulge 22 so that the pressure exerted on the resilient rods 12, 13, 18 is somewhat reduced and the cover is moved upwards again a certain distance as a result. Only when the crank pin 8 strikes against the upwardly curved end 23 of the lever 9 does the cover snap shut completely and is held in place in a known manner by snapping the hook 24 into place. The disengagement of the clutch is taken care of by the cover itself, which is released in a known manner (cf. German Patent 91454) at the end of the work process and which is opened again under the action of the spring 15. For this purpose, a stop 51 is arranged on the extension 14 of the same, which is intended to hit the above-mentioned, firmly connected lever 45, which causes the clutch to disengage, when the cover is opened. When the clutch is engaged, the latter has been shifted inward so that it is located below the cover extension 51. Towards the end of the upward movement of the cover, the extension 51 encounters the lever 45 located below it and rotates it downwards. The consequence of this is that the coupling moves in the same way as previously described, only in reverse, i.e. H. is disengaged. Simultaneously with this, the linkage 47, which is fixedly connected to the lever 45, also moves. the foot lever 46 upwards again, so that all parts have now returned to their starting position. It can be seen that a considerable saving in both time and force is obtained by the new machine. While up to now at least three manipulations were necessary for each work step, and the person working on the machine had to have relatively large physical strength, now the operator of the machine has nothing more to do than to bring in the dough and engage the clutch.
